feat: add Tower Log narrative event feed (Fixes #7)

Adds the tower_log DB table, a narrateEvent method on AgentService (Haiku-powered, stub-safe), a tower-log service that persists and broadcasts entries, a GET /api/tower-log REST endpoint, WebSocket bootstrap and real-time push, and a bottom-sheet Tower Log panel in the-matrix UI with fade-in animations and auto-scroll.
